    Current status of e-health in Kenya and emerging global research trends 1
    (2012) Juma, Kilwake; Nahason, Matoke; Apollo, Waliaro; Gregory, Wanyembi; Patrick, Ogao
    Healthcare delivery is being transformed by advances in e-Health which is now recognized as an essential enabler for support of health systems across the world, acting not only as an agent for reforming healthcare systems, but also as an enabling tool to share resources among countries with similar challenges without having to duplicate efforts. Lack of interoperable health systems and consensus on data standards is one of the major barriers to the use of health information. Mobile phone use has seen tremendous growth across the developing world offering opportunities to engage e-Health applications. This paper looks at the status of e-Health in Kenya exploring the efforts the government has put in place to create a conducive environment for e-Health and also explores the global research trends in e-Health. The study is carried out through an examination of scientific research papers in journals and conference proceedings. Additionally, telephone interviews with the Ministries of Health, and Public Health and Sanitation is carried out to gauge the level of adoption. The study seems to reveal that though e-Health in Kenya is still in its infancy, the potential for its growth is enormous. This is fuelled by the rapid penetration of mobile phone use, an educated and entrepreneurial populace, and conducive legal, regulatory, and infrastructural environments.

    Evaluating total cost of ownership for university enterprise resource planning: case of Maseno university
    (2015) Owoche, Patrick Oduor; Gregory, Wanyembi; Juma, Kilwake Humphrey
    Higher learning institutions (HEI) are investing in IT to attain operational excellence. Organizations looking to reduce technology costs typically look for ways to reduce the Total Cost of Ownership (TCO). TCO captures all direct and indirect costs related to deploying a particular system. Understanding life-cycle costs provides opportunity to save scarce resources, improve IT and increase productivity. The study sought to analyze the TCO of university ERP system. The TCO analysis was based on Gartner’s TCO model, the Distributed Computing Chart of Account as the theoretical framework. Modified Gartner TCO model was used to determine the total cost of owning Maseno University ERP system. The aim of the study was to create awareness on life-cycle costs of ERP solutions. The results obtained indicate that operations and maintenance account for 51%, end-user usage 23% while technology acquisition costs accounted for 16 %, implementation costs with 7% and the least cost was taken by procurements costs with 3%. Case study was used in gathering both qualitative and quantitative data from Maseno University. Interviews, document analysis, and questionnaires were used to gather the research data. It is hoped that the results of this study will help HEIs improve management of their ERP systems.
